Mike, Catonano,
Thank you, friends! I have solved my issue before you answered, though I'm grateful to you both. I am going to use the solution suggested by Mike and approved by Catonano if/when I will have similar problems in future. I think, the recipe by Mike would go to the Guile texinfo manual and be helpful for many Guile users/devs. WDYT? -- Vladimir (λ)επτόν EDA — https://github.com/lepton-eda
